[SOLVED] How to rerender block (model) in this situation OR different solution?

Hello, I have created a C4 explosive block. I managed to have it rotate and/or flip in any direction depending on the side and direction it is placed on.

The problem: when I reload the world/Minecraft the rotation is not saved.

Important: the variables: side and facing are saved in the TileEntity correctly!

I hope that somehow refreshing (rerendering) the block will fix my problem.

Thanks.

 

BlockC4.class

public class BlockC4 extends BlockContainer
{
    public static final Material c4 = new Material(MapColor.tntColor);
    private int side;

    protected BlockC4()
    {
        super(c4);
        setBlockName(BlockData.C4_UNLOCALIZED);
        setStepSound(soundTypeGrass);
    }

    @Override
    public int onBlockPlaced(World world, int x, int y, int z, int side, float hitX, float hitY, float hitZ, int meta)
    {
        this.side = side;
        return super.onBlockPlaced(world, x, y, z, side, hitX, hitY, hitZ, meta);
    }

    @Override
    public void onBlockPlacedBy(World world, int x, int y, int z, EntityLivingBase entityLivingBase, ItemStack itemStack)
    {
        TileEntityC4 tileEntityC4 = (TileEntityC4) world.getTileEntity(x, y, z);
        int facing = MathHelper.floor_double((double) ((entityLivingBase.rotationYaw * 4F) / 360F) + 0.5D) & 3;
        tileEntityC4.facing = facing;
        tileEntityC4.side = side;
        world.setBlockMetadataWithNotify(x, y, z, facing, 2);
    }

    @Override
    public void onBlockDestroyedByExplosion(World world, int x, int y, int z, Explosion explosion)
    {
        if (!world.isRemote)
        {
            world.setBlockToAir(x, y, z);
            world.createExplosion(null, x, y, z, 6.0F, true);
        }
    }

    @Override
    public TileEntity createNewTileEntity(World world, int var2)
    {
        return new TileEntityC4();
    }

    @Override
    public int getRenderType()
    {
        return -1;
    }

    @Override

        return false;
    }
}

        super.readFromNBT(tag);

In conclusion [if anyone had the same problem], I managed to sync the data (variables) by adding this:

 

TileEntityC4.class

@Override
    public void onDataPacket(NetworkManager net, S35PacketUpdateTileEntity pkt)
    {
        NBTTagCompound tag = pkt.func_148857_g();
        facing = tag.getInteger("facing");
        side = tag.getInteger("side");
    }

    @Override
    public Packet getDescriptionPacket()
    {
        NBTTagCompound tag = new NBTTagCompound();
        writeToNBT(tag);

        return new S35PacketUpdateTileEntity(xCoord, yCoord, zCoord, blockMetadata, tag);
    }

 

Everything renders and rerenders correctly now!

 

EDIT: removed useless schedule block update.
